Problems solved by technology

However, because the upper and lower ends of the common wedge gate have the same thickness, the stress and strain are not the same. The strain stress at the upper end is greater than that at the lower end, so the upper end becomes the weak link of the seal, and leakage is prone to occur here.

Embodiment Construction

[0014] as attached figure 1 As shown, a gradual veneer structure of a wedge-type ram includes a veneer whose thickness gradually increases from the lower end of the ram to the upper end of the ram.

[0015] The change of the gradual thickening is uniform.

[0016] The gradient thickening described above is based on the angle θ as the standard for gradual thickening

[0017] The angle θ ranges from 3° to 10°.

[0018] The preferred value of the angle θ is 5°.

[0019] The gradual single-plate structure of the wedge-type ram is aimed at uniform-thickness rams.

[0020] The strength and rigidity of the sealing surface at the upper end (2) of the gate plate are enhanced.

[0021] A gradual single-plate structure of a wedge-type ram. The main design points of the structure are the upper end of the ram, the lower end of the ram, and the single plate. The specific instructions are as follows:

[0022] In view of the fact that the sealing surface of the uniform-thickness ram and...

Abstract

The invention belongs to the field of industrial valves, and particularly relates to a gradual change type single board structure of a wedge-type flashboard. The gradual change type single board structure of the wedge-type flashboard comprises a single board, and the thickness of the single board is gradually increased from the lower end of the flashboard to the upper end of the flashboard. The structure has the remarkable effects that the strength and rigidity of the sealing surface at the upper end of the flashboard are improved, and the situation that the leakage rate exceeds the standard due to the fact that the upper end of the flashboard is large in strain during working is avoided.

Description

technical field [0001] The application of the present invention belongs to the field of industrial valves, and in particular relates to a gradual single-plate structure of a wedge gate. Background technique [0002] The leakage of the main sealing surface of the gate valve usually occurs at the upper end of the sealing surface of the gate outlet end. When the valve is closed, the static pressure of the medium pushes the gate to the valve seat at the outlet end, and the axial force of the valve acts on the forced sealing of the gate to achieve the sealing effect. However, because the upper and lower ends of the ordinary wedge gate are the same thickness, the stress and strain are not the same. The strain stress at the upper end is greater than that at the lower end, so the upper end becomes the weak link of the seal, and leakage is prone to occur here. The gate is designed so that the thickness of the single plate gradually increases from the lower end to the upper end of th...
